HIGH RANGE SUPERPLASTICIZER

Specco W-66 is a multi-component superplasticizing admixture that will provide a high degree of water reduction to concrete. W-66 will allow easy flowability and pumping of high slump concrete with increased early and final strengths and improved workability. W-66 may be used in ready mix, mobile mix, block, precast, pre-stressed, concrete, mortars, and grouts.

BENEFITS:

Allows low water to cement ratios.

Improved compressive strengths at all ages.

Less bleeding and easer workability.

Provides denser concrete with less permeability.

COMPOSITION: MLow viscosity, A.E.A. modified naphthalene based plasticizer. W-66 does not contain any calcium chloride or intentionally added chlorides that would initiate or promote corrosion of reinforcement steel, or contribute to efflorescence.

TECHNICAL DATA: Specco W-66 is formulated to comply with ASTM C-494 Type A and F guidelines. W-66 is typically dosed at 16-24 oz. per 100 lbs. of cement (1040-1560 ml/100 kg) for most applications. The dosage can be increased as needed to allow more flowability along with corresponding higher percents of water reduction. Specco recommends a field test or trial mix be run in order to determine the optimum dosage needed for the specified slump requirements.
